Make browser history work
Description
Currently, our HTMX-based calculator application doesn't properly integrate with browser history functionality. When users perform calculations, the browser's back and forward buttons don't work as expected, and the URL doesn't update to reflect the current state of the application.
Problem
- When users click the browser's back button after performing calculations, they don't return to their previous calculation state
- Calculations aren't bookmarkable via URLs
- Users can't share specific calculation states via links
- Browser refresh causes loss of calculation history
Desired Outcome
- Implement HTMX's history extension to maintain proper browser history
- Each calculation should update the URL with a unique, shareable state
- Browser back/forward buttons should navigate through calculation history
- Page refreshes should restore the current calculation state
Implementation Details
- Integrate HTMX's
hx-push-urlattribute to update browser URL with each calculation - Use
hx-historyextension to manage browser history - Ensure Django backend can handle direct URL access to specific calculation states
- May require storing calculation state in the URL or implementing a state restoration mechanism
- Consider using SolveHistory model to maintain calculation history
Acceptance Criteria
- Browser back button navigates to previous calculation state
- Browser forward button navigates to next calculation state
- URLs are updated with each calculation and are shareable
- Page refresh maintains current calculation state
- All existing calculator functionality continues to work properly
